No that's redpill bullshit. You can have all the money you want, you can be a nerdy weirdo and have a good body but number one thing that matters the most is the face and then comes the height. None of the things you mentioned can come even close in importnace level to the facial attractivness and height. As for self-confidence and mental strength, how can you be confident when no one even bothers to spit in your face. Also if you are a normie or a subhuman, acting confident will make you look even weirder in girls' eyes.
